Perc Dry Cleaners Co-Located in Residential Buildings Must Be Phased Out by 2020

In July, 2006 USEPA issued standards (40 CFR 63.322) that included phase-out of perchloroethylene (perc) dry-cleaning solvent machines located in residential buildings by December 21, 2020. Dry cleaners using perc machines located in residential buildings (co-located) will be prohibited from using perc and should begin planning to switch to alternative cleaning methods such as wet cleaning, carbon dioxide or hydrocarbon technology or relocate the perc dry cleaning solvent machines. Perc is an organic solvent of known human toxicity and USEPA reasoned that perc dry cleaners located in residential buildings posed the greatest risk to the general public.
